A new engine numbering system began this year. The

first two letters designated the manufacturing plant:

PM (Mound Road)

PT (Trenton)

OW (Windsor)

The next three digits indicated displacement: 170,225,318, etc.

The next letter designated model:

R (regular gas)

L (low compression)

T (standard-duty)

H (heavyduty)

The next four digits designated the date of manufacture, based

on a 10,000-day calendar. Last came a four-digit sequence number

for each day's production, starting with 0000 for LA318 engines and

5000 for all others.

• **Example:** [PT318T22040008]

This engine would be made in Trenton, with 318 cid displacement, standard compression, the eighth engine built on day no. 2204.

Serial numbers were on a plate on the left door lock pillar.

The 10-character number consisted of four elements. The first two

digits gave model code; the third digit was number of cylinders (6 or

8). The fourth digit showed assembly plant (1 for Warren Truck; 2 for

Warren heavy-duty; 6 for Windsor; or 7 for Missouri). The final six

digits made up the sequence number.

Model codes were as follows:

11 (D100)

*Starting and ending sequence numbers are not available.

Engine numbers were located as follows:

(six) right side of block, below no. 1 spark plug;

(318 V-8) left side of block, below cylinder head;

(383 V-8) right side of block, adjacent to distributor.

Two engine numbering systems were used.

The 170 and 225 cid six-cylinder and 318 cid V·8 engines were identified as follows: First two letters indicated manufacturing plant

(GM=Mound Road; GT=Trenton; NM=Marysville; GW=Windsor).

Next three digits showed displacement. Next letter gave engine type

(R=regular 318 cid V-8; T=standard 225 cid six; H=premium 225 cid

six).

Next came a four-digit manufacturing date code based on a

10,000-day calendar. The final four digits were the sequence number,

which began with 0001 for each day.

The 383cid V-8 and other engines were identified as follows:

First letter indicated model year;

next letter indicated engine type (T=standard; H=premium);

next three digits, displacement;

next digit, assembly plant shift;

next four digits, manufacture date;

next two letters, non-standard engine indicator;

followed by four-digit sequence number.

*Starting and ending engine numbers are not available.

Serial numbers were on a plate on the left door lock pillar.

The 13-characternumber consisted of seven elements: First two characters, model code; next digit, Body Code; next letter indicated GVW rating (A, 6000 Ibs. or less; B, 6,001 to 10,001Ibs.; C, 10,001 to 14,000 lbs.); next letter indicated engine displacement; next digit showed model year; next letter was assembly plant; and final six digits were the sequence number.
